SULKY-PLOW.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed .April 10, 1911. Serial No. 620,183.

To all whom t may concern Be it known that I, IVILLIAM L. PAUL, of SouthBend, in the county of St. Joseph and State of Indiana, have inventedcertain new and useful Improvements in Sulky- Plows; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in sulky plows, and moreparticularly to such as embody in their construction, a crank aXlehaving a journal mounted in the hub of a land wheel, and a verticallymovable standardaXle having a slanting journal mounted in the hub of theslanting furrow wheel.

The object of my present invention is to provide simple and efficientoperatingdevices for sulky plows of the class specified, whereby bothwheels can be moved simultaneously to raise or lower the plow, with theuse of a single lever, and to construct the mechanism that the furrowwheel can be separately adjusted relatively to the land wheel with theuse of a lever provided for this specific purpose.

I/Vith this object in view, the invention consists in certain novelfeatures of construction and combinations of parts as hereinafterdescribed and pointed out in the claims.

yIn the accompanying drawings, Figure 1 is a side elevation of a sulkyplow embodying my improvements. Fig. 2 is a plan view of the same, andFig. 3 is a transverse sectional View.

1 represents a plow beam constructed at its rear end with a standard 2with which the soil engaging member 3 is connected. Brackets 4-5 aresecured to the beam and project'laterally therefrom respectively inopposite directions,-said brackets, together with a smaller bracket 6secured to the bracket l5 and to the beam, constituting a frame for theaccommodation of various parts of the plow mechanism. A crank axle 7 ismounted in the brackets 4 and 6 and provided at its outer end with ajournal 8 which is mounted in the hub of a land wheel 9.

To the outer end of the bracket 5, a tubular casting 10 (preferablyrectangular in cross-section) is secured and serves to guide avertically disposed standardaxle 11,- the latter hL ving at its lowerend a slanting journal 12 mounted in the hub of a slanting furrow wheel13. The end of the crank aXle 7 which is mounted in the bracket 6 isprovided with an arm 14 and the shank 15 of a guide loop 16 is looselymounted in said arm-,fsaid shank passing transversely through the arm. Abar or rod 17 has sliding movement through the guide loop 16 and ispivotally attached at its upper end to the standard-axle 11 near theupper end of the latter. The rod or bar 17 carries a toothed segment 18to be engaged by a detent 19 carried by a lever 20. The lever 2O ispivotally attached a comparatively short distance from its lower orforward end, to the rod or bar 17. Beyond its pivotal connection withthe rod or bar 17, the lever 20 is bent slightly upward and pivotallyconnected with the upper end of a pitman is attached to the shank 15 ofthe guideloop 16.

To the outer end of the bracket 4: (which is adjacent to the land wheel)a toothed segment 22 is secured. A lever 23 is mounted on the crank axle7 and secured to the crank arm thereof by means of a bar 24V-said lever23 being provided with a detent 25 to engage the teeth of the segment22.

With the construction and arrangement of parts above described, it willreadily be seen that when the lever 20 is in locked relation to thesegment 18 and the lever 23 is operated, the crank-axle will be turnedto effect the raising or lowering of the plow. Assuming that the lever23 has been moved in a direction to cause the raising'of the plow, thecrank-axle operating through the medium of the land wheel will raisethat side of the structure and simultaneously, motion will be impartedby the arm 14 to the pitman 21 to move the latter ldownwardly and saidpitman being connected with the locked lever 2O which in turn isconnected through the rod or bar 17 with the standard aXle 10, thelatter will be moved downwardly and, through the medium of the furrowwheel 13 resting on the ground, cause thatside of the structure to beraised. Should it be desired to adjust the furrow wheel with relation tothe land wheel, this can be 21, the lower end of which latter Aaccomplished by means of the lever 20. It is apparent that if the lever2O be moved downwardly from the position shown in F ig. l, theV standardaxle l0 will also be moved downwardly and the furrow wheel side of themachine will be raised independently of the land wheel side. Of course,should the lever 2O be moved in the other direction, the standard axle10 would be raised and result in the lowering of the furrow wheel sideof the structure relatively to the land wheel side.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is,

l. The combination with the land and furrow wheels of a sulky plow, acrank axle having one of said wheels journaled on its crank arm, andprovided at its opposite end with a crank arm, and a lever and sectorrack for rotating the crank axle, of a vertically adjustable standardaxle having one of said wheels journaled thereon, a guide connected withsaid crank arm, a sliding bar pivoted at its upper end to the standardaxle and its lower end arranged to slide in said guide, a sector rackconnected with the` slidmg arm, an operating lever pivoted to thesliding arm, and a pitman pivotally connected at its upper end to theoperating lever and at its lower end to said guide, substantially as setforth.

2. In a plow, the combination with a frame and a soil engaging member,of a crank-axle mounted in said frame, a wheel having the journal ofsaid crank axle mounted in its hub, the crank-axle, a vertically movablestandard axle provided at its lower end with a journal, a furrow wheelin which said journal is mounted, a rod or bar connected with thestandard axle and having sliding connection with the arm at the adjacentend of the crank axle, a lever pivoted to said rod or bar, a segmentconnected with said rod an arm at the opposite end of or bar and adaptedfor coperation with said lever, apitman connected with said lever andwith the arm at the adjacent end of the crank axle7 a lever secured tothe crank axle, and a toothed segment secured to the frame forcooperation with a detent carried by said last mentioned lever.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
